BinaryJson

An ooc implemention of KLab's Binary JSON.

Introduction

The original description can be found in KLab's game engine PlaygroundOSS. This engine hasn't been updated for a while but almost everything is still being used in KLab's game, such as school idol festival.

Feature

• Compact
• Simple(only 500 lines)
• No Dependency(only use ooc/sdk)
• Fast

Description

Everyting(Int, String, Object...) is a JsonNode. You can get its value through JsonNode get. By JsonNode toString, json node can be translated to a normal json file. Even though JsonNode provides addVal and addKey, they only work for Object and Array.

To modify the content of a JsonNode, access data directly. (Will be updated in future)

To parse a binary-json, use class BJson. BJson will parse a binary-json file into JsonNode, and save results in BJson root. Notice that root is a JsonArray. It means if your json file is a single-object, you should use BJson root data[0].

Usage

Currently it only accepts BinarySequenceReader

Convert a binary-json in memory to text:

fw := FileWriter new(args[1])
br := BinarySequenceReader new(BufferReader new(Buffer new(buf, buflength)))
// choose file endianness
// br endianness = ENDIANNESS big 
json := BJson new(br)
fw write(json root toString())
fw close()

TODO

• More tests
• Add get ~index and operator overload for array/object
• endianness safe
